Question

How to print the characters need to be removed so that two strings become anagram in Kotlin

Answer 1

fun printCharactersNeedToBeRemovedForAnagram(str1: String, str2: String) {
    val charCounts = mutableMapOf<Char, Int>()

    // Count character frequencies in both strings
    (str1 + str2).forEach { ch ->
        charCounts[ch] = charCounts.getOrDefault(ch, 0) + 1
    }

    // Print characters with odd counts (not forming pairs)
    for ((ch, count) in charCounts) {
        if (count % 2 != 0) {
            print("$ch ")
        }
    }
}

fun main() {
	val str1 = "masterfx"
	val str2 = "ksampret"

	printCharactersNeedToBeRemovedForAnagram(str1, str2)
}
